Referring to, which show a sex toyaccording to one embodiment according to the present disclosure. The sex toyincludes an outer tubeand an inner tubedisposed inside of the outer tube. The inner tubeis hollow and defines a stimulation chambertherein for receiving a male penis. In this embodiment, the stimulation chamberis cylindrical. The inner tubeincludes soft materials at least facing toward the stimulation chamber. An accommodating chamberis formed between the outer tubeand the inner tube. At least two massage arms,are disposed in the accommodating chamber. The at least two massage arms include a first massage armand a second massage armdisposed on radial opposite sides of the inner tuberespectively.

Exemplarily, the outer tubeis substantially a hollow cylindrical structure. The inner tubeis entirely made of soft materials. The accommodating chamberbetween the outer tubeand the inner tubeis used to place massage arms,and a drive assembly. The drive assemblyis in torque-transmission connection with the at least two massage arms,, for driving the first massage armand the second massage armto slide towards or away from each other. The first massage armand the second massage armare respectively disposed on opposite radial sides of the inner tube. A guide membermay be fixed on the outer tubefor guiding the movement directions of the first massage armand second massage arm

The first massage armand the second massage armin the present embodiment can slide towards or away from each other. When the first and second massage arms,slides towards each other, they press the inner tubeinwardly towards the stimulation chamber, so as to narrow the radial size of the stimulation chamberand pinch the male penis received therein.

In other words, a pinching function that simulates a human hand holding and kneading the male penis is achieved by sliding movement of the above embodiment of the present disclosure. Furthermore, the present disclosure also provides another embodiment that simulates male penis by rolling function.

In another embodiment of the present disclosure, as shown in, a sex toy is provided, including a hollow support baseand a first massage portionarranged within the support base. The support basehas an massage spaceextending in an axial direction of the support basefor receiving a male penis. Preferably, the massage spacehas a central axis Q extending in the axial direction. The support basealso has an entranceat a first axial end of the massage spacefor insertion of the penis. The first massage portionincludes at least one first rotatable massage rollerand at least one second rotatable massage roller. The at least one first rollerand the at least one second rollerare arranged in the massage space, opposite to and spaced from each other with a gapdefined between the at least one first rollerand the at least one second roller. Preferably, each massage rolleris a solid of revolution, i.e., a three-dimensional structure formed by rotating a two-dimensional planar figure 360 degrees about an axis.

When the penis is inserted in the massage spacein the axial direction, a portion of the penis is disposed in the gapand sandwiched by the at least one first rollerand the at least one second roller, such that the at least one first rollerand the at least one second rollersimultaneously stimulate two opposite sides of the penis through circumferential surfaces of the massage rollerswhen they rotate. That is, when the massage rollersrotate, the portions of the circumferential surface of each massage rollercontact and stimulate the penis in sequence to simultaneously stimulate a respective side of the penis.

Compared with the prior art, the penis can be inserted through the entranceof the support baseinto the gapbetween the at least one first rollerand the at least one second roller, sandwiched by the at least one first rollerand the at least one second roller. When the massage rollersrotate, they simultaneously achieve rolling massage stimulations on opposite sides of the penis.

The massage rollermay be rotatable actively, for example, upon driven by an electric motor. Alternatively, the massage rollermay be rotatable passively. That is, the rotation of the massage rolleris not caused by electric driving, rather it rotates under friction or external force applied by the male penis.

Each massage roller rotates about a rotation axis P, the orientation of which is not particularly limited in the present disclosure. In the present embodiment, as shown in, the rotation axis P of each massage rolleris arranged substantially perpendicular to the axial direction of the support base. Alternatively, the rotation axis P of each massage rollermay be arranged at an angle relative to the axial direction of the support base. In case that the massage rollersare rotatable upon driven by an electric motor, the rotation axis P of the massage rollermay be arranged parallel to the axial direction of the support base.

Preferably, the sex toy may include a second massage portionarranged in the massage space. The second massage portionis arranged spaced from the first massage portionin the axial direction. Preferably, the second massage portionis located adjacent to a second axial end of the first massage portion.

Preferably, the sex toy may include a clamping mechanismfor adjusting a position of the massage roller. More preferably, the sex toy may include a drive mechanismfor driving the clamping mechanismto move axially.

The at least one first rollerand the at least one second rollerof the first massage portionare configured to massage a first part of the penis, particularly the middle portion of the penis. The second massage portionis provided with a massage cavityfor accommodating and massaging a different second part of the penis, particularly the glans. The penis can be inserted through the entranceinto both the first massage portionthe second massage portionone after another.

The clamping mechanismis configured for driving the at least one first rollerand the at least one second rollerto move in a direction at an angle relative to the axial direction of the support base. The drive mechanismis configured for driving the clamping mechanismto move along the axial direction of the support base. The massage cavityof the second massage portionextends axially. The second massage portionhas a massage area formed at an inner periphery thereof surrounding the massage cavityfor massaging the penis inserted therein.

In yet another embodiment, as shown in, the support baseis shaped as a hollow cylinder. The sex toy further includes an annular lipsurrounding the circumference of entrance. The lipis made of a flexible material, which enhances contact area with the penis and provides an improved wrapping sensation. Therefore, the support baseserves as the supporting structure of the entire sex toy, providing a mounting foundation for other components, ensuring structural stability of the entire sex toy during operation.

In one embodiment, each massage rolleris mounted on the clamping mechanism, which in turn is connected to the drive mechanism. The drive mechanismis mounted to the support baseand is configured to drive the clamping mechanismto move along the axial direction of the support base. Simultaneously, the clamping mechanismis connected to each massage rollerby its own mechanical structure, serving not only to support each massage rollerbut also to achieve movement of each massage rolleralong a lateral direction of the support basewhen driven. The lateral direction is parallel to the plane which is perpendicular to the axial direction of the support base. The position and shape of the massage cavityis designed according to physiological structure of the penis, for example, as shown in, both ends of the massage cavityalong the axial direction of the support baseare open. This design facilitates insertion of the penis into the massage cavityto receive massage from the second massage portion. The second massage portionmay have a corresponding mounting structure, enabling the second massage portionto securely mount to the support baseand locate at an optimal position for coordinated operation with the first massage portion.

Upon activation of the sex toy, the drive mechanismis initially activated to drive the clamping mechanismto move along the axial direction of the support base, which enables the at least one first rollerand the at least one second rollerto be positioned corresponding to an extended range in the axial direction, thereby applicable for different lengths of penises.

Simultaneously, the clamping mechanismoperates according to preset programming or user input, and the at least one first rollerand the at least one second rolleris stably driven by the clamping mechanismto move along the lateral direction of the support base. Such radial movement can adjust the size of the gapbetween the at least one first rollerand the at least one second rollerso as to adapt for different penises with different radial dimensions. Through precise controlling the movement of the clamping mechanism, the at least one first rollerand the at least one second rollercan be adjusted to an optimal location, thereby providing an appropriate initial massage position for provide improved contact with various parts of the penis.

When the at least one first rollerand the at least one second rollerreach the target position, the massage action begins. Preferably, each massage rollermay incorporate a vibration motor therein, which generates vibrational energy for massaging penis. Additionally, each massage rollermay achieve a reciprocate motion through a cam mechanism driven by a motor, thereby simulating manual kneading actions like that in the embodiment shown in. There is also another massage manner that may alternatively be employed, including but not limited to electromagnetic actuation to generate pulsed massage motions.

With respect to the second massage portion, when the penis is inserted into the massage cavity, the second massage portioncan operate independent from the first massage portion. The second massage portionmay include elements disposed on the inner wall of the massage cavityto provide the stimulation. The elements may include air bags, massage balls or the like, which operate through inflation, deflation, or rotational motion to provide massage for the penis within the massage cavity.

For example, when air bags are implemented, an air pump is employed to alternatively inflate and deflate the chambers of the air bags, whereby the expansion and contraction of the chambers generate cyclical compressive and decompressive massage effects on the penis. Alternatively, when massage balls are implemented, an electric motor may drive the balls to rotate or vibrate, thereby providing frictional stimulation on the penis.

Preferably, the second massage portionis made of a flexible material, enabling a better fit for the contour of the penis, thereby enhancing the user comfort during massage. In addition, the second massage portionmay be driven by a driving element, which includes, but is not limited to, a vibration generator for driving the second massage portionto vibrate, a rotational actuator for driving the second massage portionto rotate, a linear actuator for driving the second massage portionto reciprocate axially, or a vacuum system for creating negative pressure within the massage cavityof the second massage portion.

In some embodiments, the sex toy of the present disclosure achieves multi-stimulation for the penis through the cooperation between the first massage portionand the second massage portion, thereby providing a more diversified massage experience.

In some embodiments, the drive mechanismand clamping mechanismin the first massage portioncan flexibly adjust the position of the at least one first roller andthe at least one second roller, enabling the at least one first rollerand the at least one second rollerto move both axially and radially. This allows precise adjustment according to different users' penis length and thickness, improving the adaptability and personalization of the massage, expanding the applicable population range, and better satisfying the needs of different users.

In some embodiment, the at least one first rollerand the at least one second rollercan employ multiple massage modes, increasing the effectiveness of the massage. For example, through the combination of various massage modes such as vibration, kneading, and pulsation, the sexual stimulation effect can be further enhanced.

In some embodiment, the massage cavitydesign of the second massage portioncan provide better positioning and fixation for the penis, improving the precision of the massage. Meanwhile, the internal massage mechanism of the second massage portioncan perform targeted massage according to different parts of the penis. The second massage portioncooperates with the first massage portion, which forms a relatively complete penis massage system, making the massage more comprehensive and integrated, and further enhancing comfort and sexual stimulation effects.

Furthermore, the drive mechanismis arranged to the axial direction of the support base, enabling the first massage portionto move precisely along the axial direction, which can better adapt to the penises of different lengths, and ensure that the at least one first rollerand the at least one second rollercan cover the entire range of penis lengths for massaging. As a result, it greatly improves the applicability of the sex toy and meets the individual needs of different users.

In one embodiment, the support baseis provided with a partition. The second massage portionand each massage rollerare arranged above the partition, and the drive mechanismand clamping mechanismare arranged below the partition. The partitionis provided with a groovecorresponding to each massage roller, for providing moving space for the massage rollers. Specifically, the partitionis fixed to the support baseand divides the massage spaceof the support baseinto an upper part and a lower part. The partitionmay be connected to the support baseby welding, screwing, snapping, or other means to form a stable structure, providing support and positioning base for other components.

The second massage portionis arranged above the partitionand may be connected directly to the partitionor via a support structure to ensure a stable position. For example, the bottom of the second massage portionmay be fixed to upper surface of the partitionthrough bolts or clamping slots to prevent displacement during use. The position of the second massage portionis determined based on the actual requirements of the penis massaging, so as to facilitate the insertion of the penis into its massage cavityfor massage. The height and orientation of the second massage portionon the support baseshould match the comfortable position of the penis inserted, thereby ensuring massage effects and users experience.

The drive mechanismand the clamping mechanismare positioned below the partition, which not only facilitates the concealment and protection of internal transmission components but also utilizes the partitionas a support structure to optimize the overall space layout of the device.

The grooveon the partitionis located below each massage rollerand provides space for the movement of each massage roller. The shape and size of the grooveare designed according to the motion range and track of each massage roller, ensuring that each massage rollerdoes not interfere with the partitionduring radial movement. The groovemay be rectangular, circular, or other shapes, and its position and size are precisely matched with the motion range of each massage rollerto ensure smooth movement of each massage rollerabove the partitionduring operation. In some embodiments, two groovesmay be provided for the two massage rollersrespectively. In some embodiments, the two groovescan be integrated as one groove, that is, only one groovemay be provided for both the two massage rollers.

In the embodiment shown in, each massage rolleris connected to and driven by a massage motor assembly. The massage motor assemblyis arranged at a moving endof the clamping mechanism. The massage rolleris connected to the output end of the massage motor assembly.

The massage motor assemblymay be fixed on the moving endof the clamping mechanismvia bolts, snaps, or other fastening means to prevent loosening or displacement during operation. The moving endof the clamping mechanismis configured to drive the massage motor assemblyto move in the lateral direction of the support base, thereby allowing the massage motor assemblyto adjust its position following the movement of the clamping mechanismto meet the massage requirements for different parts of the penis.

In the embodiments in which the massage rollersare rotatable actively, the massage motor assemblyincludes a first motor. The massage rollermay be mounted around the output shaft of the first motorin a rotation-proof manner. That is, relative rotation between the massage rollerand the output shaft of the first motoris prevented, such that rotation of the output shaft of the first motorwill cause synchronous rotation of the massage roller.

In some embodiments, the massage rollermay be fixedly mounted to the output shaft of the first motorby means of a key, a pin, or the like to ensure that the torque from the first motorcan be effectively transmitted to the massage roller. Alternatively, the massage rollermay be fixed to the output shaft through interference fit or form-fitting.

After being connected to the output end of the first motor, the massage rollercan rotate under the drive of the first motor, thereby achieving stimulation on the penis.

In some embodiments, the massage motor assemblymay include a vibration motor. The massage rollercan be connected to the vibrating part of the vibration motor. The vibrations generated by the vibration motorare transmitted to the massage rollerthrough a specific connecting structure, causing it to generate corresponding vibration stimulation. When driven by the vibration motor, the massage rollercontacts the penis with high-frequency vibrations, stimulating the penis through the impact force and frequency variations of the vibrations.

In some embodiments, as shown in, the massage motor assemblyincludes a vibration motor, a first motor, and a first motor gearbox. The vibration motor, first motor, and first motor gearboxare all located within the massage rollerand are arranged one after another along a direction away from the moving end. The first motordrives the massage rollerto rotate through the first motor gearbox.

In some embodiments, each massage rollermay include a rigid rolling core, and a flexible layer. The flexible layeris made of a flexible material and is wrapped over the rolling core. Specifically, by providing the flexible layeron the surface of the rolling core, a soft contact is provided to the penis, which increases the comfort of the user and improves the user experience. In addition, the flexible layermay be provided with protrusions or textures on its surface, which can increase friction and therefore enhance the stimulating effect. Specifically, in the embodiment shown in, the surface of the flexible layeris provided with a plurality of ribs spaced apart along its rotational direction.
